My experience with Dr. Smile started even before my first appointment to scan my teeth on the 25th November. In fact, I was in contact with one of their competitor, which was not smart enough to block a great deal, trying to increase the price and use sales strategy like "only until today you ahve 50 € discount" that our of over a 1.000 € is actually a joke, but also not being clear on the costs [they told me a price at the stand and then changed it via whatsapp].
After this bas experience I had at the IAMExpats in Den Haag in October 2022, I contacted Dr. Smile and everything went smoothly. I picked the closer dentist in Amsterdam Noord, and in one week I received the plan, the scan and I was contacted by one of their sales person. Even with the 400 € Groupon discount though, I still paid 1.290 € for a (super) light plan of 4 months including a one-tooth reduction that I disagree with and I asked for a solution without this option, which was sent to me straight after. In fact, I actually had to move only tooth n. 22, as I already wore braces twice (mobile and fixed) when I was 9-11 yrs old, but when you move 1 tooth, you still need to make sure that the others move accordingly. I blocked the deal and received the aligners in December, starting to wear them on the 28th December 2022.
After about 2 months, everything was still going smoothly, and I contacted the same sales person to understand what to do about the retainers as I wanted to have them on time when I was finished with aligner n. 8 (my last one). I was not called back and I tried to contact him a month later. Another person from their team (I guess) called me back and then sent me a follow up email with 2 links: 1. to book the retainers online and 2. to book an appointment with the dentist to do another scan and check if I could have a fixed retainer also on the upper jaw (this was my ultimate goal, but I discovered that my bite was too tight to be able to do so)
In the end the second link was not working for 90% of the dentists as it seems that this service is still not 100% implemented in The Netherlands. I then found one dentist only that was "kind of in a good position" from where I live, but different than the first one I did the scan at.
They confirmed that I could not have a fixed retainer in the upper jaw, but only in the bottom jaw, therefore I booked the 3 mobile upper retainers which arrived 19 calendar days later. As they were not really responsive within that timeframe, I did the fixed lower retainer directly at my dentist, and it was also cheaper. It took a bit less than 30 minutes.

Overall it was a good experience, even if I think that tooth n. 22 still needs a slightly further move and I would have appreciated a bit more responsiveness when I became a client, as I was only listened when I was simply a prospect. Therefore a suggestion for the Dr. Smile Team: customers are your best allies, you should take care of them, because they make your business grow!
